Final Answer : A, Explanation :  The larger the difference between the means of two samples, the more likely it is that the difference is statistically significant. This is because a larger difference means there is less overlap between the two distributions, making it more unlikely that the difference occurred by chance. The other options are not necessarily indicative of statistical significance; large standard deviations may increase variability within each sample, making it harder to detect a significant difference, and samples drawn from the same population may have identical means. Sample means being larger than sample medians is also not necessarily related to statistical significance.
